Looking for advice: Starting seeds indoors & hardening off

Post  BackRiver_SFG on 2/20/2012, 1:38 pm

Trying to get a jump start on the season, so I am starting seeds inside this year under florescent lights on which are on timers.

All seedlings are good for cold weather here.
I am using fluorescent lights. Two tubes covering the full spectrum between the 2 of them.
Using a timer the seedlings are getting 14 hours of light a day. Too much??? To little???

The seedlings will be set in my cold frame.

I hope to have black spray painted milk jugs with water in them IN the cold frame for heat retention.

Any advice for the hardening off process or experience would be appreciated.

14 hours is practically perfect. The lights really need to be close, within 2 inches of the tops of the seedling. This will prevent the plants from getting too leggy. If you transfer them to the cold frame you may want to throw a sheet of plastic over it for a few days to allow them to not become sunburned. When it's time to harden them off, you will open the frame during the days and allow them exposure. Give them a few days out of the cold frame before setting into the garden. There is a lot of good advice on the web.
